Slide 3 - Tekstslide

At the end of lesson

... you can explain how plants hold energy in glucose during photosynthesis.

... you can explain that breaking down glucose releases energy.

Slide 4 - Tekstslide

Maarten van der Weijden

195 km in 4 days!

Where did he get the energy from?
What role did the respiratory system play?

Slide 5 - Tekstslide

Sunlight energy

Slide 6 - Tekstslide

Where do we get energy from?

make notes

Slide 7 - Tekstslide

Where do we get energy from?

water + CO2+ sunlight → glucose + O2

converting substances into other substances = metabolism

make notes

Slide 8 - Tekstslide

Slide 9 - Video

How does energy come free?

Glucose can be broken down. This happens in the mitochondria.

Important! Both plant and Animal Cells have mitochondria.

Energy comes free when glucose is broken down. This process is called combustion.
